Background
Increased muscle tone is a common complication of cns disorders, in which increased muscle tone occurs in 50-80% of stroke patients, and in some patients, even for life. The increase in muscle tone is manifested by spasm of limbs, which seriously affects the patient's ability to perform daily activities and rehabilitation. A person with high muscle tension exhibits an abnormal posture both in exercise and in rest, and the motor function of the patient is impaired over the long term. Therefore, in the spastic period, it is very necessary to perform early rehabilitation training on the patient along with the abnormal increase of the muscle tension of the patient, and the commonly used rehabilitation means include antispasmodic limb position, joint mobility training, slow traction of spastic muscles, rehabilitation aid therapy, and the like. Rehabilitation aids such as splints and orthoses have been widely used clinically in recent years and have been proven to be a rehabilitation means effective in reducing muscle tone. Meanwhile, the patient needs to perform accurate muscle tension evaluation of the hemiplegic limb in the rehabilitation training period, which not only can effectively understand the spasticity of the limb, but also is a prerequisite for establishing a normal motion mode after the hemiplegic limb, preventing the formation of disability and improving the rehabilitation efficacy. Currently, the most common clinical evaluation method for abnormal increase of muscle tone in each disease stage after stroke is an improved Ashworth rating scale which has been applied for many years and has good efficacy and reliability, but the method has strong subjectivity, and different therapists often have differences in examination results according to own experience and proficiency, so the scale cannot accurately and objectively evaluate the muscle spasm state of a patient.
Aiming at the current situation that a quantitative muscle tension measuring device is lacked at home and abroad at present, a device capable of quantitatively measuring muscle tension is urgently needed to be researched, so that manpower and material resources can be greatly reduced to a certain extent, the rehabilitation level is improved, the significance of the clinical diagnosis technology is great, and the device is a huge gospel for the rehabilitation of hemiplegia patients.
